The end side is, as described above, the first blower 9
It is connected to the. Therefore, the air discharged from the first exhaust port 97 passes through the exhaust box 62, the first duct 7, and is returned to the first blower 9 again.

Further, as shown in FIG. 12, dust and the like mixed in the air discharged from the inside of the collecting device 5 is not discharged to the first duct 7 on the upper surface of the first exhaust port 97. A substantially rectangular first filter 63 having an area slightly larger than that of the first exhaust port 97 is provided. The first filter 63 is adapted to be inserted horizontally between the exhaust box 62 and the collecting device 5 from the right side in the drawing. Further, a second filter 64 is provided between the exhaust box 62 and the cylindrical member 62a. The second filter 64 is configured by stacking three filter members, and in the present embodiment, three filters of 5, 7, and 10 mm are stacked. The number of filters and the mesh size are not limited to these, and can be changed.

Next, the inside of the collecting device 5 will be described with reference to FIGS. 4, 10 and 11. As shown in FIG. 4, a flat plate 78 is pivotally supported by a rotating shaft portion 79 near the lower side of the receiving port 24 provided on the first wall surface 91 of the collecting device 5 to which the second belt conveyor 4 is connected. As a result, the flat plate 78 is rotatable. Further, inside the collecting device 5, there is provided a net-like floor plate 84 having a plane parallel to the ground and having a large number of openings. Further, as shown in FIG. 12, the first wall surface 9 of the collecting device 5 is
Guide beams 80a and 80c extend upward from the laying plate 84 in the approximate center of the first and third wall surfaces 93 and near the fourth wall surface 94. Meanwhile, similarly,
In the vicinity of the fifth wall surface 95 side, guide beams 80b and 80d extend upward from the spread plate 84. Then, the guide beams 80a and 80c, the guide beams 80b and 80d
Between the three partition plates 8 having a substantially rectangular mesh.
1, 82, 83 are provided so as to be sandwiched. As shown in FIG. 10, the partition plates 81, 82, and 83 are vertically stacked so that the height of the partition plates can be adjusted.

As described above, the inside of the collecting device 5 is
The first room 76, the second room 77, and the third room depending on each member.
The room 75 is divided into different rooms, and the dirt is accumulated in each room according to the size and weight of the dirt as described later. In the first room 76, mainly heavy and large-sized dust (eg, large pieces of wood) accumulates. In the second room 77, dust that is blown to a position away from the receiving port 24 of the collecting device 5, that is, dust that is light and small (for example, waste paper, vinyl, waste plastic, etc.) is accumulated. Then, in the third room 75, sand attached to dust or the like is dropped and accumulated.

Furthermore, the fifth part, which is the rear surface of the collecting device 5, is
A back plate 87 having a surface parallel to the fifth wall surface 95 is provided on the wall surface 95 at a distance of about 50 mm from the fifth wall surface 95. Further, since the back plate 87 has a net-like shape having a large number of openings, the air blown into the collecting device 5 can pass through not only the floor plate 84 and the first exhaust port 97 but also the back plate 87. You can Therefore, when dust or the like is accumulated on the spread plate 84, the mesh of the spread plate 84 is blocked by the dust and the air circulation is deteriorated. It is possible to perform a sorting process. Also, here, the back plate 8
7 is provided at a distance of 50 mm from the fifth wall surface 95, but this distance is not limited to this and may be changed.

Further, a ladder portion 90 is connected to the outside of the third wall surface 93 of the collecting device 5. This is because it is easy to climb the second wall surface 92 of the collecting device 5 by using the ladder portion 90 and perform replacement work when confirming damage or distortion of the separation wire net 12 and exchanging members. It is like this.

Next, a mechanism for sorting the residual soil of the sorting apparatus 1 will be described. First, the process of selecting the residual soil from the separation wire net 12 to the collecting device 5 will be described. First,
As shown in FIG. 1, the residual soil to be sorted is supplied to the upper surface of the separation wire net 12 fixed to the tilt adjusting frame 14. The remaining soil is a separation wire mesh 1 that vibrates by a vibration motor 13.
Soil flowing over 2 and having a particle size smaller than the mesh is separated wire mesh 1.
2 falls on the first belt conveyor 2 installed just below 2, is conveyed from the inside of the tilt adjusting frame 14 toward the outside, and is accumulated. On the other hand, a residue having a particle size larger than the mesh of the separation wire net 12 flows on the separation wire net 12. Further, since the gravitational acceleration is applied to the residue, the residue flowing on the separation wire net 12 collides with the drop absorbing section 20 installed on the second belt conveyor 4, and falls on the second belt conveyor 4. Then, the residue is conveyed in the direction of the magnetic separator 3 by the second belt conveyor 4, but the magnetic separator (iron piece , Nails, cans, etc.)
Residues are deposited below the end of the belt conveyor 4. The residues deposited here are mainly large, heavy crushed stones and the like.

Further, the residue dropped from the separating wire net 12 to the second belt conveyor 4 and conveyed is the first in a direction opposite to the direction in which the residue is conveyed by the second belt conveyor 4. Since it is blown by the blower 9 of the above, light dust in the residue (for example, vinyl, waste paper, waste plastic, etc.)
Are skipped in a direction opposite to the conveying direction of the second belt conveyor 4. Further, since the first blower 9 blows air toward the inside of the first cover portion 8, even if dust adhering to dust rises due to the blown air, it is shielded by the first cover portion 8 Dust will not scatter. Then, the dust in the residue blown out by the first blower 9 is blown along the inside of the first cover portion 8 and reaches the receiving port 24 of the collecting device 5.

Next, a flow of sorting dust and the like in the collecting device 5 will be described. First, as shown in FIG. 1, dust and the like sent out from the connecting portion with the second belt conveyor 4 is blown into the inside of the collecting device 5 through the receiving port 24. As shown in FIG. 11, dust or the like blown into the receiving port 24 is blown along the plane direction of the flat plate 78 provided at the lower part of the receiving port 24. At this time, heavy dust falls directly under the flat plate 78, and relatively light dust (for example, vinyl, waste paper, waste plastic, etc.) is thrown away from the receiving port 24. Therefore, heavy and large-sized dust (for example, wood chips) is accumulated in the first room 76, and light, small-sized dust is accumulated in the second room 77. In addition, the sand adhering to the respective dusts passes through the floor plate 84, and the third room 7
Accumulate to 5. Further, since the flat plate 78 also has a mesh shape having a large number of openings, the sand also falls into the third chamber 75 from the mesh of the flat plate 78.

The air blown into the collecting device 5 is discharged to the outside through the first exhaust port 97, and the air is returned to the first blower 9 through the first duct 7. Further, the first filter 63 and the second filter 64 of the first exhaust port 97 are configured to filter dust mixed in the discharged air. Therefore, since dust and the like are not discharged into the first duct 7, dust and the like are not mixed in the air blown from the first blower 9.

Further, as the residual soil sorting process is continued, dust and the like are accumulated in the collecting device 5. Then, since the ratio of accumulated dust inside the collection device 5 increases, the space (gap) in the collection device 5 becomes narrow. However, since the amount of air sent to the collection device 5 (the amount of air blown by the first blower 9) does not change, turbulence of air occurs in the narrow space inside the collection device 5, and dust accumulated in each room is regenerated. It will be mixed. Therefore, when dust starts to accumulate in the collecting device 5, the partition plates 81, 82, 83 in the substantially central portion of the collecting device 5 are stacked in the upward direction.
For example, as shown in FIG. 10, partition plates 81 and 82 are stacked to form a first chamber 76 and a second chamber 77 of the collecting device 5.
Partition and to about 2/3 height. This should be piled up to the height at which garbage is accumulated. Then, the dust accumulated in each of the first chamber 76 and the second chamber 77 serves as a partition by the mesh of the partition plates 81, 82, and 83, so that the respective dusts can be prevented from being mixed.

When dust or the like sent out inside the collecting device 5 starts to accumulate, a pile of dust or the like is formed in the first room 76, for example. The mountain formed by the dust and the like becomes a large wall, and the dust and the like blown from the inlet 24 collide with the mountain and accumulate there. Therefore, as dust and the like accumulate, the surface of the flat plate 78 is adjusted upward so that no pile of dust is formed in one place. Therefore, since the dust is evenly accumulated in the first room 76 and the second room 77, the selection processing of the residual soil can be continued without lowering the selection processing capability of the collection device 5.

Further, when dust or the like is accumulated in the collecting device 5, the dust or the like blocks the mesh of the laying plate 84 and the ventilation of the collecting device 5 is deteriorated, but the back plate 87 has many openings. Since it has a net-like shape, air also escapes from the back plate 87, and ventilation inside the collecting device 5 is maintained. Therefore, even if the sorting process is continuously performed, the processing capacity does not decrease.

Next, a collecting device 500 which is a modification of the collecting device 5 in the sorting device 1 will be described with reference to FIG. FIG. 13 shows the left and right door portions 610 of the collecting device 500,

Furthermore, the first wall surface 91 of the collecting device 500
At 0, a blower opening 242 having a substantially rectangular shape is provided in the lower part of the inlet 240. In addition, the third filter 2 is attached to the air outlet 242 so that dust and foreign matters do not flow from the outside to the inside of the collecting device 500 through the air outlet 242.
43 is fixed. The third filter 243 is slightly larger than the area of the air outlet 242, and the air outlet 2
All 42 are covered with the third filter 243. Further, a blower stand 608a is connected to the outside of the collecting device 500 and near the lower side of the blower opening 242,
The second blower 608 is fixed to the blower base 608a at a predetermined angle. Specifically, when the second blower 608 blows air from the blower port 242 toward the inside of the collecting device 500, the second blower 608 is directed obliquely upward so as to blow toward the back surface side of the flat plate 780. It is fixed.

Room 770 of each. The sprinkler 651 is capable of spraying the entire inside of the collecting device 500.

When the sorting process is performed by the collecting device 500, the angle of the flat plate 780 in the collecting device 500 is fixed slightly above the horizontal plane. This is because the dust blown from the receiving port 240 reaches the second chamber 770 as much as possible and is transported to the outside by the third belt conveyor 200. Also, large and heavy trash (for example,
(Wood chips, etc.) fall from the flat plate 780, and the collecting device 500
Accumulate within. When a large amount of large dust accumulates in the first room 760, two of the three partition plates are stacked to partition the first room 760 and the second room 770.
The dust accumulated in the first room 760 and the dust conveyed to the third belt conveyor 200 are prevented from being mixed.

Next, a flow of sorting the dust in the collecting apparatus 500 will be described with reference to FIG. The collecting device 500 has all the structures and functions of the collecting device 5. First, dust is blown from the receiving port 240 of the collecting device 500. Further, the blown dust passes on a net-shaped flat plate 780 having many openings. Here, since the second blower 608 blows air toward the back surface side of the flat plate 780 through the blower port 242, light dust is directed toward the third belt conveyor 200 along a substantially extended line of the surface of the flat plate 780. Be skipped. On the other hand, large and heavy dust immediately falls near the lower part of the flat plate 780 and accumulates. Further, the sand or the like attached to the dust falls below the net-like spread plate 840 having many openings and accumulates.

Then, the dust flying toward the third belt conveyor 200 is guided to the third belt conveyor 200 by the hopper 202 and falls. Further, the dust that has fallen onto the third belt conveyor 200 is conveyed toward the third wall surface 930, passes through the discarding port 623, and is conveyed to the outside of the collecting device 500. At this time, since the internal air is expelled from the waste port 623 to the outside, dust attached to the dust rises. However, since the outside of the third belt conveyor 200 is covered with the second cover portion 622, dust is not scattered around. Further, the air in the second cover part 622 is
The second exhaust port (not shown) passes through the exhaust box 621 and the second duct 700 and is returned to the second blower 608, so that the air in the second cover part 622 is sucked. It has become. Therefore, the second cover portion 62
The air and dust in the second cover portion 622 are sucked from the second exhaust port. The sucked dust is returned to the second collecting device 500 again by the second blower 608 through the second duct 700.

Then, dust is not scattered from the dust on the third belt conveyor 200 which is transported through the inside of the second cover portion 622, and the transported dust is the third dust. The belt conveyor 200 is adapted to fall from the leading end side in the conveying direction to a downward direction and accumulate. The dust accumulated here is mainly vinyl, waste paper, waste plastics, and the like.

When the sorting process is continued for a long time, dust is blown up inside the collecting device 500, and the mesh of the net-like base plate 840 having a large number of openings and the mesh-like back plate having a large number of openings causes the eyes of sand or dust to be caught. Clogs occur. Then, the flow of air in the collecting device 500 becomes poor and the sorting process cannot be performed well. Therefore, the water sprinkling device 6 is provided at approximately the center of the second wall surface 920 that constitutes the upper surface of the collecting device 500.
51 is provided, the spray nozzle 651a is the entire first chamber 760, and the spray nozzle 651b is the second chamber 77.
It is designed to spray mist-like water over the whole area. When the sprinkler 651 is operated, the collector 50
0 Mist-like water is sprayed over the entire interior. Then, the dust inside the collecting device 500 absorbs the water, and the weight of the dust becomes heavy, and the dust falls and can be suppressed. Further, it is possible to eliminate the clogging of the floor plate 840, the back plate 870, and the like.

The present invention is not limited to the above embodiment, but various modifications can be made. For example, the number of partition plates 81 to 83 of the collecting device 5 is three, but any number may be used, and each of them is vertically connected by fixing each with a string or the like and pulling up each fixing portion from the outside of the collecting device 5. In this way, the height of the partition plate may be adjustable. In addition, as the size of the belt conveyor, a large belt conveyor may be used depending on the amount of residual soil to be processed. In that case, it is advisable to install several blowers on the belt conveyor to improve the processing capacity. Further, although the flat plate, the floor plate, the partition plate, and the back plate described in this embodiment are wire nets having a net diameter of 10 mm, the net diameter may be changed according to the size of the object to be selected. Well, each mesh diameter may be different from each other. Further, although the collecting device 5 is a box having a substantially rectangular parallelepiped shape having no bottom surface, a bottom surface may be provided and the sand accumulated on the bottom surface may be freely taken out.

Further, in the separation wire net 12, the elongated beams 34a and 34b of the tilt adjusting frame 14 are extended upward, and the fitting holes 41 provided in the long side beams 31a and the long side beams 31b, respectively.

Further, in the above-mentioned embodiment, the receiving port 24 of the collecting device 5 is connected to the side surface of the end portion of the second belt conveyor 4, and the air flowing from the first blower 9 is
Is bent at a right angle by the cover part 8 of the collecting device 5 and blown into the receiving port 24 of the collecting device 5, but the receiving port 24 of the collecting device 5 is arranged on the extension of the second belt conveyor 4 in the length direction. The collecting device 5 may be arranged as described above. At this time, the second belt conveyor 4 and the collecting device 5 are arranged on a substantially straight line. The installation location of the collecting device 5 may be freely changed according to the surrounding environment where the sorting device 1 is installed.
